I'm planning to R&R my stainless rub rail to re-bed it and correct any loose fasteners. I've discovered that the tapping screws attaching the rail are metric. Best I can determine they are 5.5M x 65. If I convert them to a #12 screw that is the closest match, the head will stand proud of the rail enough to grab any surface I rub against (rarely occurs ) and perhaps could even pull a screw sideways or otherwise create damage. There are 46 screws per side, so modifying the countersink isn't practical, not under consideration. If that's not enough, I believe I really should use 316 SS with the constant exposure to seawater. I'm striking out on locating metric tapping screws in 316.
Any suggestions WRT sourcing the hardware? Dimensions on the attached.
